WATER QUALITY REPORT WHAT DO WE TEST FOR?

Transcription

1 WHAT IS THIS REPORT? This report is to let you - our customers - know that water produced by meets or exceeds all standards for safe, high-quality water. is required by drinking water regulations to make this water quality report available to customers. It s like a nutritional label for the substance you probably consume the most - water! WATER QUALITY REPORT This data and information can be complex, so we ve tried to make it readable while also including the required language. Congress, the EPA, and want to be sure that consumers know what s in their drinking water. WHAT DO WE TEST FOR? tests for over 100 regulated and unregulated contaminants in drinking water. Our state-of-the art water quality lab runs over 120,000 tests on 18,000 water samples each year to ensure the finest water reaches our customers taps. All data in this report is from If a known health-related contaminant is not listed in this report, did not detect it in the water. HOW MUCH WATER DOES WATERONE PRODUCE? In 2013, treated approximately 10.7 billion gallons of Kansas River water, 2.5 billion gallons of Missouri River water, 8.7 billion gallons from its Wolcott Collector Well (adjacent to the Missouri River), and 0.9 billion gallons of water from collector wells south of the Kansas River. customers consume an average of million gallons per day (MGD), depending on the time of year. The most water consumed in one day was MGD, set on July 23, HOW CAN I GET WATER ALERTS? 2014 Sign-up for water alerts at Customize your contact info, alert preferences, and tag your locations - home, work, school, etc. You ll automatically get a phone, text, or if we need to take water down for maintenance or emergency repair as well as important water quality or water use alerts.

2 WATER AT A GLANCE ALL DRINKING WATER, including bottled water, can reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. In order to ensure that tap water is safe to drink, the EPA has regulations that limit the amount of certain contaminants in water provided by public water systems and require monitoring for these contaminants. More information about contaminants and potential health effects can be found at the Environmental Protection Agency s Safe Drinking Water Hotline at 800/ or at Ensuring Safe, Reliable Water Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, persons with HIV/AIDS or other immune system disorders, some elderly people, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. Guidelines from the Environmental Protection Agency (EPA) and Centers for Disease Control and Prevention (CDC) on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at 800/ Our Treatment Process 1. Aeration - Raw water is drawn from our fresh water sources - the Kansas and Missouri Rivers and adjacent collector wells - and collects in our presedimentation holding basins, allowing large debris particles to settle out. 2. Coagulation/Flocculation - Water is transferred to mixing basins at our treatment plants where we add alum and polymer. This process causes small organic particles to clump together, forming larger particles (flocculation). 3. Sedimentation - Over time, the nowlarger particles become heavy, settle to the bottom, and get strained out. Depending on the profile of the raw water at the time, we may add lime or soda ash to counteract calcium and magnesium, softening the water. Water is then transferred to a second clarifier where we add carbon dioxide to balance ph and treat it again to flocculate and strain sediment clumps. 4. Filtration - Water filters through layers of fine, granular materials anthracite coal and sand filters. As smaller, suspended particles are removed, cloudiness diminishes and clear water emerges. 5. Disinfection - To protect against bacteria and other microbes, disinfectant is added before the water flows into the distribution system - clean, fresh, and delicious. Fluoride occurs naturally in our water but also is supplemented in the treated water. WATER QUALITY DATA TERMS, ABBREVIATIONS & SYMBOLS Some of the terms used in this report are unique to the water industry and might not be familiar to all customers. Explanations are provided below. Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. Maximum Contaminant Level (MCL): The highest level of a contaminant allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum Residual Disinfectant Level Goal (MRDLG): The level of drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants. Not Detected (ND): Not detected in the water. Nephelometric Turbidity Units (NTU): A measure of the clarity of water. Picocuries per liter (pci/l): A measure of radioactivity. Parts per million (ppm): Or milligrams per liter. Parts per billion (ppb): Or micrograms per liter. Parts per trillion (ppt): Or nanograms per liter. ph Units: A measure of acidity or basicity of the water. Saturation Index (S.I.): Measure of corrosivity. Secondary Maximum Contaminant Level (SMCL): Secondary MCLs for various water quality indicators are established to protect public welfare. Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water. µmhos/cm: Or micromhos/cm; a measure of the ability of a solution to carry an electric current. Sources of Drinking Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, and ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. Contaminants in drinking water sources may include: Microbial contaminants, such as viruses and bacteria, which may come from wildlife or septic systems. Inorganic contaminants, such as salts and metals, which can occur naturally or result from urban stormwater runoff, industrial or domestic wastewater discharges or farming. Pesticides and herbicides, which may come from a variety of sources such as farming, urban stormwater runoff and home or business use. Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes, and can also come from gas stations, urban stormwater runoff and septic systems. Radioactive contaminants, which can occur naturally.

Maximum residual compliance is based on monthly averages. s highest value, 4.4 ppm, was an instantaneous reading. 2. Data from 2013 annual monitoring, though not required by a reduced monitoring schedule as a result of low levels of lead and copper. This value is the 90th percentile result. The 95th percentile value for lead is 7.0 ppb; the 95th percentile value for copper is ppm. 3. TOC removal ratio is calculated as the ratio between the actual TOC removal achieved and the TOC rule removal requirements. 4. This is the highest turbidity measurement for Compliance is based on 95% of monthly samples being less than 0.3 NTU. The average turbidity was less than 0.10 NTU. Turbidity is measured as an indicator of the effectiveness of the water treatment process. The lower the turbidity, the more effective the treatment process. 5. EPA considers 50 pci/l to be the level of concern for beta particles.
